    Smile Re: Leak from bottom of DE filter.

    Phillbo, I'm a 'Hayward guy' (all 4 companies I've worked for have primarily used Hayward products). I have seen pin-holes in the stainless steel tanks , but it's probably the pipe on the bottom/ it's connection that's the problem. It could be as simple as just having to re-teflon tape the male thread or something may have cracked. I think you should plan on the cleaning when the hardware store is still open so you can get any adapters or pipe you may need. If it's a part/ piece you can't replace you can probably limp by with a 2 part epoxy patch for a while (if you don't feel like ordering and replacing a part right now).

    I hope that it's something that can be fixed with a few wraps of teflon - if it's more serious, I'll help as best I can

    Do you know if Pentair has bought out Nautilus ? I've been searching the net to try and locate a locale dealer for parts and the search for Nautilus FNS only returns Pentair FNS results...

    I believe this is the case - I have a Nautilus NS-36 and all the parts I've needed to order for it have come in Pentair packaging.

    Try here for parts; I've never ordered through them but they have nice schematics of the filters and seem to have a huge parts selection:

    Thanks for clarifying the Pentair mystery judas.

    I came across that site earlier. I'm guessing i'll need part number 23 but will have to wait until I can tear into it to be sure..

    Was unable to find anyone that had a tool to remove the big nut at the bottom of the tank holding the manifold / o-ring assembly I needed to remove, a couple different shops told me it would leak again so due to the age of the unit, I opted to go for a new unit.

    Installed the new Pentair FNS Plus 48 DE Filter last night.
